Past couple of days have been more brain-work than finger-work, but I did do some real work today. I did a test wiring of my rear wiring board. First, I diagrammed where all the wires should go (see this PDF). Next, I inserted the DMOC wiring harness into its flexguard, crimped terminals on the ends of its wires (as well as the 8-in-1 wiring harness), and test-fit it all together (the 8-in-1 at least will have to come off again before it gets attached permanently):
Still need to wire the potbox on as well as the wires from the original Porsche harness.
